The tiny financial advisory firm quietly advising them on deals behind the scenes: Allen & Co.
The firm worked on the initial public offering of Ferrari which priced on Tuesday night.
It is also an adviser on the flotation of Match Group, which is behind some of the world's biggest dating apps and websites.
Those are just the latest in a long line of landmark roles for the firm. It has previously worked on deals for the likes of Facebook and Google.
The firm shuns the spotlight. It has no website (this one belongs to a different company), and employs fewer than 200 people. A spokesperson for the firm did not respond to a call seeking comment in time for publication.
Herbert Allen Junior led the company for years, and has a seat on the board of Coca-Cola. His son Herb Allen III, who is now CEO at the firm, was named on Vanity Fair's new establishment list in 2012.
Many of the deals the company works on are birthed during the firm's secretive annual Sun Valley Conference, which is sometimes described as the "Billionaire's Summer Camp." Hollywood celebrities mingle with CEOs like Bill Gates and Elon Musk.
Here is a list the firm's best known clients.
